IMPROVEMENT IN GLOD-GRUSHERS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, DR. T. H. ASHTON, of Defiance, county of Defiance, and State of Ohio, have invented certain new and useful Improvements in Clod-Crushers and Harrows, andl do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, and the letters of reference marked thereon, making part of this specification.

i Figure 1 is atop plan view, showing the barrows and arrangement of rollers. I

Figure 2 is an end view. The nature of my invention consists in so combining, with a double-triangular barrow-frame, clod-cutting or crushing rollers, that the large lumps or clods'of soil are completely broken before the same are subjected to the action of the barrow.

The rollers are provided with teeth similar to those of the burrow, and in their action not only crush the 'clods, but, by slightly compressing the soiL Ieave the same smooth for the passageofthe barrow. By. my

arrangement it will be seen that the clods are not only crushed, but, by the combining of the rollers in the manner shown, the implement is adapted to any surface, no matter how great its undulations may be.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

A'A are two triangular barrow-frames, and are constructed in the usual manner, and provided with teeth a a. These frames are united bymeans'of a metallic connecting-rod, B, which has its bearings in eyes I; b and e a, and is firmly held in position by means of nuts 12.

b b are metallic eyes, which are firmly attached to the beams A A, near their rear end.

The eyes 0 c are cast with or firmly secured to the plates C G.

C C are metallic plates, andare firmly bolted to the forward end of'the beams A A.

c c are openings in the end of the plates 0 G, in which rests one of the bearing-pins d of the roller D.

C C are clevis-hooks or links, and are also cast with or attached to the plates C C.

D D are circular or octagonal-faced rollers, and are provided with numerous teeth, E E, as clearly shown in the drawing.

This roller works between metallic plates C and F, being secured to the opening 0 in the plate C-by means of the headed pin 02, and to the plate F by means of the opening e and bearing-pinf. The plate F is made of metal, and is firmly bolted to the beams A and A of the barrow-frames A A. This plate F is cast or made in the form shown in fig. 1, and is provided with a bearing-pin or rod,f, which enters and works in the opening e of the roller D. p

It will readily suggest itself to any skilful mechanic that numerous devices are in use whereby the rollers .could be readily attached to the barrows, whereby the implement would operate with equal success; "therefore I do not desire to be understood as limiting myself to the precise method shown.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

The double barrows A A and rollers D D, when the same are so combined and arranged as topperate substantially as described, as and for the purpose specified.

In testimony whereof, I have signed my nameto this specification in the presence of two subscribing witnesses.
